Identical twins on trial: can DNA testing tell them apart?

Identical twins share identical DNA, making standard forensic DNA testing unable to distinguish which twin committed a crime, though whole-genome sequencing can identify rare post-birth mutations to differentiate them.

Humans' pull toward alcohol may have ancient origins (according to chimp pee)

Chimpanzees consume 10 pounds of fruit pulp per day on average - African star apple. It's delicious, too. I tried some. And when fruits like this ripen, they can ferment, producing alcohol. In primates, it could be that when you smell alcohol, that means that's where the sugars are.

I clicked on a button and everything changed': how a DNA test turned my life upside-down

It was another detail that the rest of the family apparently knew but had never told me; they thought I already knew. The biology mattered less to me than the secret. Dad had been adopted, it turned out. A classic affliction of the 1950s, in which young, unmarried couples were forced to give away their newborn babies.

Risk of carrying the 'Celtic curse' gene varies across Ireland, new study finds

Targeting genetic screening for the condition to priority areas could help identify at-risk individuals earlier and avoid future health complications, experts say. Haemochromatosis symptoms can evolve over decades as high iron levels in the body cause damage to organs. Early diagnosis and treatment - such as regular blood donation to reduce iron levels - is key to prevent liver damage, liver cancer and arthritis.

Maps offer neighborhood-level insight into American migration | Cornell Chronicle

That local exodus is documented by Cornell-led research that mapped annual moves between U.S. neighborhoods from 2010 to 2019 in detail 4,600 times greater than standard public data. Called MIGRATE, the new, publicly available dataset revealed that most of those displaced remained within the affected county - moves not captured in county-level public migration data aggregated every five years.

How I Traced My Ancestor's Journey From Slavery to Freedom

The librarian sat me in front of a microfilm reader and brought out roll after roll of film. I stayed there for hours, squinting to decipher the archaic handwriting in the Free Negro Book, which was published annually in South Carolina before the Civil War. The names in each year's edition were alphabetized, but only roughly-all of the surnames starting with A came before all of the surnames starting with B, but Agee might come before Anderson, or it might come after.

'These specific symbols that are built in different size proportions, and the symbols are found in ancient stones around the world, are not supposed to exist; no cultures are supposed to have any cross-platform,' LaCroix explained. The symbols appear in locations ranging from Turkey's Van region to South America and Cambodia.

Have we leapt into commercial genetic testing without understanding it?

Martschenko's argument is largely that genetic research and data have almost always been used thus far as a justification to further entrench extant social inequalities. But we know the solutions to many of the injustices in our world-trying to lift people out of poverty, for example-and we certainly don't need more genetic research to implement them. Trejo's point is largely that more information is generally better than less.
